[A case of right ventricular dilated cardiomyopathy, which involved left ventricle].
A case of right ventricular dilated cardiomyopathy which also involved the left ventricle was reported. On health screening, a 16-year old woman was pointed out to have multifocal PVC and cardiomegaly. Subsequently, she was admitted to our hospital because of general fatigue. CTR was enlarged to 54.9% on chest X-ray. ECG showed LBBB-type PVC, right axis deviation, low voltage and T wave changes. On UCG, RVdD was dilated to 40 mm and LVdD was 37 mm. There was no finding of abnormality of the tricuspid valve. On cardiac catheterization, there was no shunt disease. Intracardiac pressure was normal. The end-diastolic volume index (ml/m2) of RV and LV was 196.7 and 67.4, respectively. And ejection fraction (%) was 20 and 40. Ventriculography revealed diffuse dilatation of the right ventricle. And lowered contractility existed not only in the right ventricle but also in the anterior and apical segment of the left ventricle. T(1)201 myocardial perfusion imaging showed irregular perfusion defect of the left ventricle. Endomyocardial biopsy revealed marked hypertrophy, partial atrophy, disarrangement of myocyte and interstitial fibrosis of the right ventricle. This case was considered to be right ventricular dilated cardiomyopathy. It seemed to be an intermediate form of dilated cardiomyopathy since it also involved the left ventricle. It was an interesting case to illustrate the spectrum of expression of cardiomyopathy.
